This axle-back is going to be a good option for you if you're looking for the most budget-friendly way to make the biggest change in your exhaust note with an axle-back. This is currently the most affordable axle-back on the site and it's a muffler delete setup, which means that this is going to give you the biggest change possible from an axle-back. The install for this is easy. It's a two out of three wrenches on the difficulty meter, but only because you do need to cut in order to install an axle-back on an S550, and you're looking at about two hours' time. This being a muffler delete system means exactly that. You're going to be completely eliminating your mufflers. So what you're going to get with this system is the pipes you see here with MBRP tips. That means that after the resonator mid-pipe, there'll be no more exhaust filtration. It's going to make for a very big change in every aspect of the exhaust sound. It's going to be much louder and deeper-sounding than the stock exhaust. There's a little bit of drone inside the cabin at cruising speeds. But honestly, I'm not surprised by that at all. The nature of a muffler delete lends itself to drone and it's not a terrible drone, but it is noticeable. With that being said, I'm going to call this one a five out of five on the loudness scale, one being a quiet upgrade, and five being a very loud upgrade. For an axle-back, you can't get much louder than this. I will say, though, that you should keep in mind that you get this volume and this sound with the stock resonator still in place. If you ever change your mid-pipe down the road, or even your headers, this system is going to get even louder and it has a potential to be very loud depending on what you do with the rest of your exhaust system. Just keep in mind the smaller diameter inlets that this axle-back has, being that it's made for the stock exhaust. The diameter of the axle-back is two and a half inches, so that it can bolt up to the factory exhaust without any issues. The tips are four-inch, polished stainless steel, and as far as materials for the rest of the axle-back, this is mandrel-bent, aluminized steel tubing. The fact that this is aluminized does help to keep the price so affordable. But you do have the downside of aluminized steel not holding up as well over time against harsher elements. This would be something that you should consider if you are shopping for a daily driver that sees all different types of road conditions. But if you're shopping for a car that only comes out during nice weather, this shouldn't completely scare you away from this product. When it comes to price, you can expect to pay very close to the $300 mark, which makes this currently the most affordable axle-back option for the S550. If you're looking for something close to this sound-wise, but you want stainless steel materials, SR Performance makes a muffler delete system for about $30 more that's stainless steel. You're going to be looking at the typical cut-and-clamp design with the install for this axle-back, since you need to cut all S550 axle-backs. I'm going to call this a two out of three wrenches on the scale, but just because of the cutting that's involved. It's nothing difficult, but I just recommend some eye protection and a fresh blade to make the cutting easier. Overall, you're looking at about two hours to get this all done. A lift would certainly make things easier for you here, but the job can be done on jack stands as well, if you don't have access to one. Cutting the factory axle-back isn't hard. Just be sure to measure twice, and plan a mark where you'll be cutting, so you don't make a mistake. Once you have the factory axle-back cut, you can drop the factory mufflers with the hangers. The new axle-back will come with new clamps for you. So you don't have to worry about transferring anything over, other than the factory hangers. Once you get the hangers over to the new axle-back, you're ready to install. You just flip the axle-back into place and bolt up the hangers. You can tighten the clamps on the axle-back. But it'd probably be easiest to leave the clamps on the tips loose until you have it all lined up, and then tighten them down. That's going to be it for the MBRP Pro Series muffler delete axle-back exhaust. But as always, you can check it out more online right here at americanmuscle.com.

Power And Performance. The MBRP Pro-Series Axle-Back Exhaust not only improves the sound of your Coyote powered Mustang, but it will also improve its performance. With the help of its free flowing muffler delete design, this Axle-Back will significantly improve exhaust flow for an increase in rear wheel horsepower and torque.

Durable Aluminized Steel Construction. Constructed from 2.5" diameter aluminized steel tubing for strength and corrosion resistance, this MBRP Cat-Back Exhaust System features two straight pipes that feature 4" slant cut exhaust tips. MBRP then completes the tips in a bright mirror polished finish for maximum visual appeal. As an added bonus, the tips are etched with the MBRP logo for true custom styling.

Cut & Clamp Installation. Installation of this MBRP Axle-Back Exhaust System will require cutting and removing the factory muffler assemblies and clamping the new muffler assemblies in place. Clamps and installation instructions are provided.

Application. This MBRP Pro Series Muffler Delete Axle-Back Exhaust is designed to fit all 2015-2017 GT Mustangs.

Like the question above, I want to install this on my MBRP h pipe that came with the full street catback system. What kind of modifications do I have to make to the existing exhaust to fit this muffler delete?

Would I still be able to pass a emission test if I remove the mufflers and add these to my gt?

Yes, emissions related tests have to do with your catalytic converters, since your mufflers are put downstream of these you should be good to go.

Is there any easy way to custom fit the MBRP Pro Series Muffler Delete Axle-Back Exhaust (15-17 GT) on a 6 cylinder 2016 mustang? I really love this product and I wish it woulds fit on my 2016 mustang v6

At this time we do not have any way to fit the MBRP Pro Series Muffler Delete Axle-Back Exhaust to a V6.

Installing the MBRP Pro-Series Muffler Delete Axle-Back Exhaust will remove the mufflers on the MBRP Cat Back Racing Exhaust, and allow you to keep your H Pipe. However, you will need to do some modification to install the exhaust.

a little louder than expected but my mustang actually sounds like a gt supposed to now. Everyone can def hear me coming. Cold start sounds like a mad throaty beast that wife just got punched in the face lol!

For low cost muffler deletes, the MBRP Pro Series set the bar. The sound is amazing and definitely turns heads. The cut and clamp installation couldn't be any simpler and the polished tips in the chrome option are badass. I'm extremely happy with these axle backs and American Muscle.

I shopped around for a few months and listened to countless videos to figure out what I wanted for an easy, quick exhaust upgrade. The MBRP Muffler delete far exceeded my expectations. The install took me about half an hour in my garage at home with a floor jack and jack stands, perfect fit no adjustments needed. When I fired it up, the exhaust boomed out really loud and deep with a nice grumble. I drive a stick and really enjoy long shifting to listen to the exhaust crackle and pop as well as downshifting it to really get the loud exhaust pops. I maintained factory resonator and haven't done any work on the headers or cats. This is a great way for me to have a car that sounds great while saving for the future mods when my warranty runs up. Very happy with the purchase.

Sounds great. I have this paired with a heartthrob h pipe and it’s loud like scare your neighbors 3 blocks away loud. Drone is loud and annoying especially at highway speeds. All said I love the sound especially when wide open it just sings.

These axle backs are amazing and really bring out the noise from the 5.0. When I got my GT one of the first things I said to myself was I need a bit more roar from my 5.0. I got these from the July 4th sale and was excited to get them installed. I paired these already roaring axle backs with a H-pipe delete reasonator, and i like the noise I get from starting it. These bad boys are excellent for the price they run for, and quick installation. I would recommend these to anyone who is just starting off and need some noise from their stock S550.

Perfect sound for the money. Nice clean, deep tone with minimal drone inside the car. When cruising around they have a nice rumble and screams when you hit the revs. Would recommend to anyone that wants a setup that is easy to live with as a daily.

My wife got me these for Christmas. Took about an hour to install. The directions were pretty clear. I did do one modification to the directions, instead of dropping the whole exhaust like the directions said, I put the back of the car on jack stands and cut the factory pipes with a reciprocating saw. There was plenty of room. The car sounds great.

This exhaust added excellent sound and loudness to my GTCS! I have had it on for two months now and it sounds perfect. I get lots of compliments on it and it was amazing bang for you buck. Only draw back is the drone on the highway is very loud. I can live with it and don't mind but at about 2100-2400 rpm it has quite a lot of drone. can be drowned out with loud music. I do love this product and happily give it 5 stars.

Now the beast is unleashed and sound is awesome doesn't take but normal tools and saw with sharp blade a little drone at speed in 6th gear but not bad for the price and now it sounds like it should have come from ford wonderful engine just needs to breathe and roar I'm a Ford guy so this is only my 2cents but I'm happy with this product and would recommend it
